Perhaps you should try some spelling variations:
"modified bayesian optimization algorithmss" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian estimation algorithm", "modified bayesian optimisation algorithms", "modified bayesian estimation algorithmss"
"designed network optimization algorithms" » "designed network optimisation algorithm", "designed network estimation algorithms", "designed network estimation algorithm", "defined network optimization algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("designed network optimization algorithms") OR ("modified bayesian optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( designed network optimization algorithms ) or ( modified bayesian optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithms") or ("modified bayesian optimization algorithmss"))*.
